I would like to use firebase to store general info on the author, submission date, and file system location (on the server). Then when the user opens the app, it will bring them to where I would curate specific photos (think IFunny, etc). I am using ionic. I need to know how I would implement a photo gallery that is always changing, and sorts photos from most recently curated (basically meaning that I like these photos and they have their own page on the app. Is there any tips y'all have for implementing this or some good theory for me to follow? I used creator.ionic and I'm going to code this feature in. Comment if you need clarification. Thanks
